WIFI wireless computer networks in classes

In classes and schools there are a lot of electromagnetic radiation sources. In a classroom with a WIFI network, and many laptops connected via the wireless network, the electromagnetic radiation levels can be very high, even if all the other EMR sources are turned off. The reason for that is the wireless WIFI router and the wireless connected laptops all emit high frequency EMR. A child who sits in this class room will be exposed to RF EMR emitted from all the laptops around him, and from the WIFI router. This is different from home WIFI use (also not recommended) in which the user is usually exposed to RF EMR only from his laptop and from the WIFI router. In addition we have to remember that children are more sensitive to EMR and are more affected by it.

Wired network is the right way. 

Wireless computer network in class simulation

The following simulation try to show how kids that will be present in a classroom with "only" 9 wireless PCs and a single wireless router will be exposed to multi frequencies (WIFI signal is spectrum spread) Radio Frequency radiation from multiple sources and from several directions. In reality kids that will be present in classes with wireless network will be espoused to multi frequencies RF radiation from the WIFI router and from many (20-40) wireless PCs, multi frequencies RF radiation from the kids' cell-phones (if permitted or if still ON), multi frequencies RF radiation from cell-phones' towers and other RF sources outside the class and to ELF magnetic fields from the electricity infrastructure. Again I remind you, the below simulation is for "only" 9 wireless computers and one wireless router.
